TO ALL WHOM IT MAY CONCERN:

Be it kno-w11 that I, JAMES SIMPSON, of St. Louis, in the county of St. Louis, and State of Missouri, have invented a new and useful Improvement in Brick-Machine; and I do hereby declare that the following is a fall, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference beingy had to the accompanying drawings, forming part of this specification.

The object of this invention is to construct a; cheap and simple machine, by which compressed brick may bemrniifactured in perfect and expeditious manner; and the invention consists in operating two compressors by cranks, which are revolved by a main shaft, and in other devices connected therewith, as will be more fully described hereinafter.

Figure 1 is a longitudinal sectional side view of the machine, the section being throughthe line yg/ of iig. 2

Figure 2 is a top or plan View, and

Figure 3 is a vertical cross-section through theline :n :o of g. 1.

Similar letters of reference indicate corresponding parts.

The parts of the machine are supported on a substantial .frame which is marked A in the drawing. B

indicates longitudinal timbers, which rest upon the frame A, and which form ways or guides for the cross-heads, which are attached tothe compressors. C is the main crank-shaft. Upon the outside of the frame, on each end of this shaft, there are crank-wheels marked D and E. a a indicate the crank-pins or wrists on theseK wheels'. F and G are thc two colnpressers. G is operated by a pitman marked c, which is attached to a crank formed on the shaft O, between the wheelsE D, as seen more distinctly in fig. 2. The compresser F is operated by two pitmenf and g, which are attached to a cross-head, t, at the outer end of the-compresser, and to the wristpine a a on the wheels E D, at the other end. J is a clay-chamber. z'is the bottom ofthe brick-chamber. m is the aperture in the bottom, through which the compressed brick are delivered. *n is an adjustable plate, by which the quantity of clay delivered irito the bricloohamber is regulated. It is adjustable by the screw o. The compressers F and G are worked respectively by their pitmen, as mentioned above, att-ached to their cranks, ,which cranks arc so placed with regard to each other, that when the compressers are at the beginning ofn. stroke, (that is, when they are farthest away from the shaft 0,) they may be suflciently far apart to allow enough clay to lie between them to form-a brick. The cranks are also so placed that while the compressers are underneath the plate n, and before arriving at the aperture m, they may approach each other as near as is required for the breadth of lthe brick. The length of the brick is determined by the breadth of the brick-chamber, and its thickness by the thickness of the compressers. From this point to the end of the stroke, they separate from nach other suiiiciently to allow the brick thus formed to fallout through theaperture m. The sides of the claychamber form grooves for the compressors to slide in. .P is an arm, which is attached to the frame at one end, as seen in the drawing. It is raised and lowered solthat its end r receives thebri'ck, (which drops through the gpm-ture m,) and deposits it on t9 a revolving apron, carryingboard, or, other means of conveyance. S is an n yrn, which is attached to P, and t a rod, which is attached toS and to the cross-head 72, as seen in tig. 1. rIhis arm S and rod t thus attached operate the arm l. i The operation of the machine is as follows: At' the beginning of the stroke, the space between the ends ot the compressors' is filled with clay, which, oi' course, will be more than enough to form a brick. As the compressors gradually approach each other, all the superiluous clay will be forced up again into the clay-chamber .-1, till the end of the compresser F reaches the plate n. All the clay now contained in the brick-chamber, (or between the ends of the compressers,) is forced into the space, (shown in red,) between them, as seen in the drawing, the compressers still travelling in the same direction, and separating over the aperture m. i

Having thus described my invention, I claim as new, and desire to'secnre by Letters Patent` 1. The combination of the vpivoted arm P, having receiving-plate r, bar S, and rod t, with the cross-head It, compressors F G, and opening m in the bottom plate z', as herein described for the purpose specied.

2. The plate n and screw o, in combination with the hopper J and compressers F G, as herein described thepurpose specified.
